Medical endoscope capsule is described from its construction principle and drive system.The scheme and function of the drive system,especially the driving velocity and the direction control for that based on FPGA,are introduced in detail.Experiments indicate that the micro-drive system,with a linear speed ranging from 0 to 10 mm/s,can move forward and backward,and turn left and right discretionarily.The availability of programmable logic device makes the system reliable and flexible.

Objective To systematically review the domestic studies on holistic nursing,so as to provide suggestions for evidence-based strategic decision about how to set upa long-term mechanism of holistic nursing.Methods The databases of China Biology Medicine (CMB),VIP,China National Knowledge Infrastructure (CNKI) and Wan Fang Data were searched to identify the relevant studies.Literatures were screened with data extraction in accordance with the predefined inclusive and exclusive criteria.The quality of literatures was assessed with the standard of Cochrane Handbook 5.0 and Crombie criteria,and the data were comprehensively analyzed with qualitative research methods.Results The total 33 cross-sectional studies were included.The results showed that the cognition of holistic nursing was good;10 literatures from the scope of business,organizational forms,strengthening the management and establish a system expounded how to implement the holistic nursing;Since our country carry out holistic nursing,effectwas significant,but there were still some problems.Discussing and solvingproblemsby using the method of evidence-basedwasthe future development direction.Conclusions The current researches about holistic nursing are lack of randomized controlled trials,most of which are the cross-sectional survey research.But the research content is wide.analyzing the present status and effect of holistic nursing,summarizing the experience and problems,promoting our country to set up a long-term mechanism of holistic nursing have the certain enlightenment function.

Objective:To observe the clinical effects of Zuoyu üo. 1(ZY1)in the prevention of concomitant concurrent complica-tions after operation for anorectal diseases. Methods:164 patients who had received operation for anorectal diseases were randomly di-vided into 2 groups. Patients in the treatment group were treated with sitz baths in ZY1 and the conventional wound dressing method. Patients in the control group were treated with sitz baths in warm water and the conventional wound dressing method. Results:The effi-ciency rate of the treatment group was significantly higher than that of the control group(53. 57% vs. 27. 5%,P<0. 05),as well as the total effectiveness(95. 23% vs. 88. 75%,P<0. 05). The comparison showed that better curative effects existed in the treatment group on distress,bleeding,and edema ratings and wound healing time. Conclusion:Sitz bath in ZY1 after operation for anorectal dis-eases reduces complications and shortens the wound healing time without any side effect. It is thus extensively promising in clinical ap-plications.

Objective To design a FPGA(Field-Programmable Gate Array)-based image & voice signal optical transmission system,which can accomplish video & audio frequency long-distance transmission.Methods FPGA was used as the main processing chip.High speed transceiver TLK2501 and SFP optical module were also used to realize high-speed serial fiber transmission.Results A non-compressed digital video optical fiber transmission system based on the TDM technology was designed.Conclusion The system achieves the real-time transmission of video and voice signals,thus greatly improving the accuracy of the examination and providing references for diagnostic experts.

OBJECTIVE To investigate the genes associated with the drug-resistance to ?-lactam antibiotics in Pseudomonas aeruginosa(PAE) isolated from clinical patients in Huaibei,Anhui Province.METHODS Antibiotic sensitivity test was performed by VITEK-AMS.The three-dimensional method was taken to differentiate various beta-lactamases.The ?-lactamases and the outer membrane protein D2(oprD2) genes were detected by polymerase chain reaction(PCR) in 36 PAE strains.RESULTS In 36 PAE strains,the positive rates of genes of TEM,DHA,CTX-Ge and CARB were 77.8%,69.2%,27.8% and 25.0%,respectively,that of the OXA-1,OXA-10,VIM-2 and IMP-1 were 16.7%,16.7%,13.9% and 2.8%,respectively.The rate of lacking oprD2 gene was 58.3%,and none possessed VEB,SHV,GES,PER,GIM and SPM-2 genes.CONCLUSIONS P.aeruginosa carries various beta-lactamase genes in clinical patients of Huaibei,and the deletion ratio of oprD2 gene is higher.

Objective To measure and evaluate slice sensitivity profile(SSP)and the full width at half-maximum(FWHM)for a 64-slice spiral CT system.Methods Using the same CT technique and body mode as those used for clinical CT,delta phantom was scanned with Somatom Sensation 64-slice spiral CT.SSPs and FWHM were measured both with reconstruction slice width of 0.6 mm at pitch = 0.50,0.75,1.00,1.25,1.50 and with reconstruction slice width of 0.6,1.0,1.5 mm at pitch = 1 respectively.Results For normal slice width of 0.6 mm,the measured FWHM,i.e.effective slice width,is 0.67,0.67,0.66,0.69,0.69 mm at different pitch.All the measured FWHM deviate less than 0.1mm from the nominal slice width.The measured SSPs are symmetrical,bell-shaped curves without far-reaching tails,and show only slight variations as a function of the spiral pitch.When reconstruction slice width increase,relative SSP become wider.Conclusions The variation of pitch hardly has effect all on SSP,effective slice width,and z-direction spatial resolution for Sensation 64-slice spiral CT system,which is helpful to optimize CT scanning protocol.

Objective To investigate the genotypes of aminoglycoside-modifying enzymes (AMEs) produced by Pseudomonas aeruginosa isolated from Huaibei Miner's General Hospital.Methods Minimum inhibitory concentration of 36 strains of P. aeruginosa to 3 aminoglycoside antibiotics was determined. AME genes were amplified by polymerase chain reaction (PCR). Results The P. aeruginosa isolates were resistant to multiple antibiotics. Most (62.2% to 81.1%) were resistant to aminoglycosides. And 27 strain (75.0%) carried one or more types of AME genes, including ant(3″)-Ⅰ (63.9%), aac(6')-Ⅱ (58.3%), aac(6')-Ⅰ (50.0%), aac(3)-Ⅱ (38.9%) and ant(2″)-Ⅰ (36.1%). The aac(3)-Ⅰ, aac(3)-Ⅲ, aac(3)-Ⅳ, aph(3')-Ⅳ genes were not identified.Conclusions The study indicates that the P. aeruginosa isolates in Huaibei are multi-resistant to aminoglycoside antibiotics. The prevalence of AMEs-positive strains is high.
